As a former XMPP fan, I think XMPP is extremely interesting in light of Moxie's recent web3 post [1], and most specifically the part: > A protocol moves much more slowly than a platform. After 30+ years, email is still unencrypted; meanwhile WhatsApp went from unencrypted to full e2ee in a year. You could replace email with XMPP in that sentence. (In fact, I'd bet Moxie was specifically thinking of XMPP when he wrote that.) I remember when Google introduced voice/video, and provided a library (libjingle) to help other clients add the feature. It never really got picked up. Perhaps it was the state of the driver ecosystem at the time that made it hard for clients to reliably support such streams (PulseAudio was still new at the time, and GStreamer wasn't as mature), that was in excess of what open-source maintainers could provide. Google eventually decided (reasonably, in retrospect and IMHO) it was easier to turn its chat into its own platform than try and drag a protocol with it. They were certainly dealing with problems that no-one else did. For example, they were very late to enable federation, much to the annoyance of the community, because Google had to deal with spam at a scale no-one else did, and wanted to make sure they had the protocols to deal with that, which no-one else in the community wanted to deal with. (Of course after that I cannot give Google any credit for their chat client merry-go-round, and they've burned any goodwill I had for them on that front! [2] ) Perhaps we'll reach a point where the feature-set for a chat client will settle, and once again a federated protocol can emerge. I no longer believe XMPP is it.

Edit: that said, I think XMPP had a lot of great ideas, and I'm glad it still pops up now and again.
